Need Help...

[Comic]

Hello everyone.
First time here.

I just bought a MSI DVD Write 8x.
I did a couple of backup of DVD movies using CloneDVd and AnyDVD with Memorex 4x DVD+R discs.
They all having the same problem while doing playback on my Panasonic SA-HT95.
For let's say the first 30 minutes or so everything is great then it starts bugging (I get scramble images and it even stops playing).
It stays like this for the rest of the movie.

I first though it was the writing speed, so I forced CloneDVD to write in 4x, but I'm still having the same problem.

Anybody having any idea?

Let me know if you need more info.

Thanks
